1 # LDAP plugin suite for Prosody
3 The LDAP plugin suite includes an authentication plugin (mod\_auth\_ldap2) and storage plugin
4 (mod\_storage\_ldap) to query against an LDAP server. It also provides a plugin library (mod\_lib\_ldap)
5 for accessing an LDAP server to make writing other LDAP-based plugins easier in the future.
9 **NOTE**: LDAP authentication currently only works with plaintext auth (as opposed to DIGEST-MD5 or SCRAM)
10 If this isn't ok with you, don't use it! (Or better yet, fix it =) )
12 With that note in mind, if you need to allow (XMPP) clients to connect to your server without TLS and
13 want to use this module, you need to set 'allow\_unencrypted\_plain\_auth' to true in your
14 configuration. You probably don't actually want to do this, though.
16 To enable LDAP authentication, set 'authentication' to 'ldap2' in your configuration file.
17 See also http://prosody.im/doc/authentication.
21 LDAP storage is currently read-only, and it only supports rosters and vCards.
23 To enable LDAP storage, set 'storage' to 'ldap' in your configuration file.
24 See also http://prosody.im/doc/storage.
28 All of the LDAP-specific configuration for the plugin set goes into an 'ldap' section
29 in the configuration. You must set the 'hostname' field in the 'ldap' section to
30 your LDAP server's location (a custom port is also accepted, so I guess it's not strictly
31 a hostname). The 'bind\_dn' and 'bind\_password' are optional if you want to bind as
32 a specific DN. There should be an example configuration included with this README, so
33 feel free to consult that.
37 The user section must contain the following keys:
39 * basedn - The base DN against which to base your LDAP queries for users.
40 * filter - An LDAP filter expression that matches users.
41 * usernamefield - The name of the attribute in an LDAP entry that contains the username.
42 * namefield - The name of the attribute in an LDAP entry that contains the user's real name.
46 The LDAP plugin suite has support for grouping (ala mod\_groups), which can be enabled via the groups
47 section in the ldap section of the configuration file. Currently, you must have at least one group.
48 The groups section must contain the following keys:
50 * basedn - The base DN against which to base your LDAP queries for groups.
51 * memberfield - The name of the attribute in an LDAP entry that contains a list of a group's members. The contents of this field
52 must match usernamefield in the user section.
53 * namefield - The name of the attribute in an LDAP entry that contains the group's name.
55 The groups section must contain at least one entry in its array section. Each entry must be a table, with the following keys:
57 * name - The name of the group that will be presented in the roster.
58 * $namefield (whatever namefield is set to is the name) - An attribute pair to match this group against.
59 * admin (optional) - whether or not this group's members are admins.
61 ## The vcard\_format section
63 The vcard\_format section is used to generate a vCard given an LDAP entry. See http://xmpp.org/extensions/xep-0054.html for
64 more information. The JABBERID field is automatically populated.
66 The key/value pairs in this table fall into three categories:
70 Some values in the vcard\_format table are simple key-value pairs, where the key corresponds to a vCard
71 entry, and the value corresponds to the attribute name in the LDAP entry for the user. The fields that
72 be configured this way are:
74 * displayname - corresponds to FN
75 * nickname - corresponds to NICKNAME
76 * birthday - corresponds to BDAY
77 * mailer - corresponds to MAILER
78 * timezone - corresponds to TZ
79 * title - corresponds to TITLE
80 * role - corresponds to ROLE
81 * note - corresponds to NOTE
82 * rev - corresponds to REV
83 * sortstring - corresponds to SORT-STRING
84 * uid - corresponds to UID
85 * url - corresponds to URL
86 * description - corresponds to DESC
88 ### Single-level fields
90 These pairs have a table as their values, and the table itself has a series of key value pairs that are translated
91 similarly to simple pairs. The fields that are configured this way are:
93 * name - corresponds to N
94 * family - corresponds to FAMILY
95 * given - corresponds toGIVEN
96 * middle - corresponds toMIDDLE
97 * prefix - corresponds toPREFIX
98 * suffix - corresponds toSUFFIX
99 * photo - corresponds to PHOTO
100 * type - corresponds to TYPE
101 * binval - corresponds to BINVAL
102 * extval - corresponds to EXTVAL
103 * geo - corresponds to GEO
104 * lat - corresponds to LAT
105 * lon - corresponds to LON
106 * logo - corresponds to LOGO
107 * type - corresponds to TYPE
108 * binval - corresponds to BINVAL
109 * extval - corresponds to EXTVAL
110 * org - corresponds to ORG
111 * orgname - corresponds to ORGNAME
112 * orgunit - corresponds to ORGUNIT
113 * sound - corresponds to SOUND
114 * phonetic - corresponds to PHONETIC
115 * binval - corresponds to BINVAL
116 * extval - corresponds to EXTVAL
117 * key - corresponds to KEY
118 * type - corresponds to TYPE
119 * cred - corresponds to CRED
121 ### Multi-level fields
123 These pairs have a table as their values, and each table itself has tables as its values. The nested tables have
124 the same key-value pairs you're used to, the only difference being that values may have a boolean as their type, which
125 converts them into an empty XML tag. I recommend looking at the example configuration for clarification.
131 For example, to get something like this in your vCard:
136 <NUMBER>555-555-5555</NUMBER>
139 Your configuration for `telephone` will probably look something like this:
144 number = 'telephoneNumber',
148 ### Unsupported vCard fields
156 ### Example Configuration
158 You can find an example configuration in the dev directory underneath the
159 directory that this file is located in.
163 This set of plugins is missing a few features, some of which are really just ideas:
165 * Implement non-plaintext authentication.
166 * Use proper LDAP binding (LuaLDAP must be patched with http://prosody.im/patches/lualdap.patch, though)
167 * Non-hardcoded LDAP groups (derive groups from LDAP queries)
168 * LDAP-based MUCs (like a private MUC per group, or something)
169 * This suite of plugins was developed with a POSIX-style setup in mind; YMMV. Patches to work with other setups are welcome!
170 * Add ability for users to change their vCard/passwords/etc from within Prosody
